Winchester 357

I have the .45 cal version and so far like it.

There are no magazines available for the .45 anywhere in the USA not sure if this is also the case for the .35. Gun comes with one magazine. Mine is having some trouble indexing after a shot or loading so I have to spin the magazine a little to got the probe/lever back into position.

The .45 is very picky on pellets slugs but from what I have read the .35 is more forgiving. 

Added a Donny FL Emperor 2 with the Evanix M18x1 adapter which helps but nit back yard friendly.

Gun is a little heavy and added a ATN x-sight Pro 4K 3-14x which makes hand held shots an issue (shooting from a blind with support).


 
I have one and like the rifle. Fit and finish is real nice and it is very accurate JSB pellets. I have tried 6 -8 cast bullets in it with marginal success. Like it is a completely different rifle than how it shoots with the pellets. It will push 150fpe with adjusting the preload on the hammer spring.


With my .45 cast bullets I get good groups with various types sizes but some of the groups are 3" right and 3" down, but tight groups. Best most consistent results with light pellets.

I would say the same for the .357. The cast bullets are a larger group, but the pellets are nearly hole on hole.
 
WEAK!

I'll take performance over looks anytime and there's just not enough FPE on the table for me to be interested.


 
A buddy spent last weekend visiting, to tune, test, and sight-in his .45 Winchester Model 70. We polished the bore, installed a depinger, and cranked up the hammer-spring pre-load to increase the power to 190-200 foot-pounds. Accuracy tested 155, 180 and 200 grain slugs. Quickly became obvious the 155 grain hollow-points were the most accurate; most three-shot groups measuring 3/4" to 1" c-t-c at 50 yards once we found the sweet-spot fill-pressure (3600 PSI) and shot only 3 shots per charge (even though it returned 5 consistent-velocity shots per charge). 

I was pretty impressed with the rifle other than within the first 100 rounds the side-lever started popping out of closed position with every shot. Didn't seem to affect velocity or accuracy though.

Thanks for this information. I have been eyeballing this platform for some time and have only heard negative about it. I would assume that most folks make no adjustments to the platform and expect it to shoot like a daystate out of the box. 

From what I have seen it appears to be similar to the Marauder platform. Can you divulge a bit more information as to the guts of the platform and what it could be capable of?
 
SS, I found the Model 70 very simple (design), easy to work on, and of nice quality in most regards. Exceptions were some tenacious crud in the barrel that was still visible even after JB Bore Paste polishing, but that didn't affect accuracy (I consider 3/4-1" groups at 50 yards excellent). The other quality issue was cosmetic; the fore-end section of the stock was visibly thinner on one side than the other.

After trying a stronger but shorter hammer-spring without desired results, we went back to the factory spring and increasing the pre-load adjustment four revolutions only got us a little more power over the factory adjustment (like 10 foot-pounds increase in power). That suggests to me the need to increase transfer-port diameter to get much more power, and I feel that might strain the platform. Loren suggests "Try backing off the hammer spring tension just a bit, and I think you will find that stops" (the side-lever popping open with each shot); again suggesting the Model 70 not the best platform for souping-up.
